Pyside QTablewidget qcheckbox点击事件

Question

我已经在 qtablewidget 的第一个单元格中添加了 qcheckbox 现在我想要的是如何访问复选框以及如何获得它的点击 event.Basically 我想要的是在复选框复选框上应该选中行并且在未选中的行上应该被取消选择。这是代码：

def add_items(self):
    rows = 5
    cols = 5
    self.tableWidget.setRowCount(5)
    self.tableWidget.setColumnCount(5)
    for r in range(0, rows):
        for c in range(1, cols):

            self.qwidget = QtGui.QWidget()
            self.checkbox = QtGui.QCheckBox()
            self.checkbox.setCheckState(QtCore.Qt.Checked)
            qhboxlayout = QtGui.QHBoxLayout(self.qwidget)
            qhboxlayout.addWidget(self.checkbox)
            qhboxlayout.setAlignment(QtCore.Qt.AlignCenter)
            qhboxlayout.setContentsMargins(0, 0, 0, 0)
            self.tableWidget.setCellWidget(r, 0, self.qwidget)

            item = QTableWidgetItem('note'+str(r))
            self.tableWidget.setItem(r, c, item)
    print 'done'

您可以使用 itemChanged 信号。

from PySide.QtCore import Slot, Qt
from PySide.QtGui import QTableWidgetItem

@Slot(QTableWidgetItem)
def on_tableWidget_itemChanged(self, item):
    """ Handles the row's state
    :type item: QTableWidgetItem
    :parameter item: The changed item
    """
    checked = item.checkState() == Qt.Checked
    if checked:  # the item gets checked
        # do stuff here..
    else:  # the item gets unchecked
        # do stuff here
